Recently we have fully installed a Many-digit number Arithmetic on 32-bit FORTH. This FORTH (ver. 2.8 of FORTH32) has various Many-digit number functions in addition to Many-digit number stack manipulations and basic arithmetic operations. By using the Many-digit number Arithmetic we have calculated Euler's constant up to 1000 digits below the decimal point. The program for this calculation is simpler than the former program based on Big-number Arithmetic, but the execution time is four times that of the former program. We also have studied a m-cycle solution (m=4, 8, ...) of May's equation, y=ax (1-x) and gotten the value of the parameter a at which a m-cycle solution occurs (m=4, 8, ..., 2^<24>) by the accuracy of 30 digits.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_2_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN10443956","subitem_source_identifier_type":"NCID"}]},"item_2_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Integrated Human Sciences"}]},"item_2_text_2":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"論文"}]},"item_2_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Article"}]},"item_2_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"人間基礎科学講座"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2005-12-20"}],"displaytype":"detail","filename":"KJ00004355530.pdf","filesize":[{"value":"590.1 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"32ビットFORTHによる多数桁数演算:完成版","objectType":"fulltext","url":"https://hsuh.repo.nii.ac.jp/record/6737/files/KJ00004355530.pdf"},"version_id":"21adc33a-b876-4f4d-971d-c1b1c1247cff"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"32ビットFORTH","subitem_subject_scheme":"Other"},{"subitem_subject":"FORTH32","subitem_subject_scheme":"Other"},{"subitem_subject":"巨大数","subitem_subject_scheme":"Other"},{"subitem_subject":"多数桁数","subitem_subject_scheme":"Other"},{"subitem_subject":"Eulerの定数","subitem_subject_scheme":"Other"},{"subitem_subject":"Mayの方程式","subitem_subject_scheme":"Other"},{"subitem_subject":"32-bit FORTH","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"FORTH32 Many-digit arithmetic","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Euler's constant","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"May's equation","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"32ビットFORTHによる多数桁数演算:完成版","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"32ビットFORTHによる多数桁数演算:完成版","subitem_title_language":"ja"},{"subitem_title":"Many-digit number Arithmetic on 32-bit FORTH","subitem_title_language":"en"}]},"item_type_id":"2","owner":"17","path":["518"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2005-12-20"},"publish_date":"2005-12-20","publish_status":"0","recid":"6737","relation_version_is_last":true,"title":["32ビットFORTHによる多数桁数演算:完成版"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-12-21T06:42:18.424839+00:00"}
